L-1011 Avionics Bending: Gables ATC Transponder Power-On Test (Video)



The Gables ATC Transponder head that I would like to use for the L-1011 project has powered up successfully. The instrument had not been in use for several years and came out of obsolete surplus. I was uncertain if it would actually work.

The device powered up fine from a 115V 400Hz source and the head consumes roughly 43 mA.

The data-output form the head is in the ARINC 429 format.
